Shear strength of one-way concrete slabs reinforced with fiber-reinforced polymer composite bars
Due to the relatively low modulus of elasticity of FRP bars, concrete members reinforced with FRP (fiber reinforced polymer) will develop wider and deeper cracks than members reinforced with steel. This research program was designed to investigate the shear capacity of one-way concrete slabs reinforced with two different types of FRP composite bars (carbon or glass FRP bars) with different reinforcement ratios. The following conclusions can be drawn: In general, the shear strength of one-way concrete slabs was proportional to the amount of longitudinal FRP reinforcement. This behavior was observed in specimens reinforced with carbon FRP bars and specimens reinforced with the two different sizes of glass FRP bars employed in this study. In addition, the results indicated that the concrete shear strength appears to be a function of the axial stiffness of the main tensile reinforcement. Both the JSCE and CSA-S806-02 design methods predict well the concrete shear strength of one-way concrete slabs reinforced with FRP composite bars as flexural reinforcement.
